Question

Write ⊂ on the blank if the first set is a proper subset of the second set and ⊄ if it is not.

{the odd whole numbers}____{the whole numbers}

Answer 1

`\sub`

Explanation:

given two sets A and B, A is a proper subset of B if every element of A is in B and A is not equal to B.

the whole numbers can be divided into two: even whole numbers and odd whole numbers. the set of odd whole numbers is contained in the set of whole numbers, but they are not equal since for example, 2 is in the set of whole numbers but not the set of odd whole numbers.

anyways this means:

the odd whole numbers are a subset of the whole numbers.
